with the snowfall that it incorporated within it. one could liken glaciers as a depositional environment, a glacial environment. in the deposits are contained events of earth history that occur simultaneously during the depositional process. you see, ice sheets are essentially atmospheric processes. practically any material passing through the atmosphere may be trapped in glaciers as they form. pollen, volcanic ash, and meteorites have been discovered in the ice. even bubbles of ancient air have been found, representing a valuable record of earth's past atmosphere and climate. since the early 1970s, an international project has been underway to drill into greenland's vast continental glacier and obtain ice core samples. called the greenland ice core program, this effort involves scientists from countries around the world. the prime difficulties in a field operation such as drilling in ice relate primarily to the climate, the weather. it's not the best place to work, but it's overcome somewhat by the technique used today to excavate trenches and cover the tops of the trenches over with some form of

, and confucius sort of emerged in this environment and said, this can't be right. and it was a combination of let's go back to the origins and understand where we came from, this instinct to go back to how did all this begin and then also to sort of develop a kind of a provision for how to order cefully re rationally, and of course confucius and taoism have radically different solutions. out of this original concept of sensing the oneness of human beings with each other and with nature the confucians came out in believing we need a government, we need an ordering of society, we need a benevolent but vertical set of relationships. whereas the taoists sort of emerged from this experience said, "that's part of the problem, in fact." human beings are trying to fix it and nature doesn't get fixed. you let nature be and if we're a part of nature, in a sense they became anarchists and the logical conclusion from the taoists is to go off into the woods and be by themselves. but in a sense nothing is - it's not a sort of like a confession where i'm a confucianist and i'm a taoists. there's a saying that,

,gro. but in a huge ring around ty slies a very different,gro. urban environment. here, stretchingoriles, is a city of self-built structures in various stages of completion. they line hillsides and rocky streets where some of sao paulo's newest immigrants struggo build mes om brick and cen where some of sao paulo's alaide and her family came to sao paulo from northeastern brazil.

. and in that environment, you have then the ejection of alpha, beta and gamma particles. so it's almost simple geometry. right now, this particle we'd call an alpha particle. this is a helium nucleus. and i'll write that helium nucleus like this. and i'll put a two down here and a four here. and this nomenclature, i hope you're familiar with. this is simply the atomic number. it tells you it's atomic number two in the periodic table of substances, yeah? it's got two positive charges. and the four refers to the atomic mass unit. and that's the number of nucleons altogether. i call this, by the way, nucleons. i can call you a people, a person, but a person can be a male or female. nucleon can be a proton or neutron. see what i'm saying? but there's four nucleons altogether, so it has a mass of four and atomic number two. so that would be the configuration. if i put another proton in there, then it would now be-- does anyone know? it would be the element lithium because now it would have three and up here would be five. and any nucleus that has three protons, by definition and by chemical properties, will

into an environment of heavy balls or light balls? heavy balls. and you want the thing to slow down. let me ask you this. if i take a ball and i throw it against a brick wall-- [makes sounds] --when it bounces off, will it bounce off a lot slower or about the same? about the same. about the same. if i take a golf ball and i throw it against a bowling ball, is that bowling ball gonna slow the golf ball down? no, it's not. so what you do is you take the golf ball and you throw into an arena of ping-pong balls. and if you do that, it will give what? give the energy to ping-pong ball and it itself will slow down. and so what do you do is you take these things and you bounce them off atoms like the size of carbon. did you ever hear about the heavy water? you bounce them off light atoms or molecules and these things will slow down, so they're moderated and will cause the reaction of more of this fission. you call--nuclear fission, gang, breaking apart, nuclear fission, and you will fission more atoms. anyway, this is something that cause an awful lot of excitement. because along with these two, it turns

environment. out to the extremely wealthy suburbs outside of chicago where every house is about a million dollars a piece and people have another set of problems and another set of challenges. well we'll go to willow creek community church and here's one that is an interesting controversy. because rev. bill hybels about 20 years ago now want - he's a christian, he's a minister, he's just starting out and he says; "why don't people go to church?" what he does, he get a bunch of his younger followers they go out and actually do a marketing approach. they go to peoples houses and ask them why don't you go to church? why don't you go to church? they come back and say "well it's boring, it's irrelevant, it doesn't do anything for me." in other words for many people churches had failed at handling those dilemmas of institutionalization. but what he did, he starts out with his tiny little church but makes it interesting, makes it entertaining as you will see, makes it relevant; if you've been there but man, keeps to that very authentic rather conservative christianity that keeps that part of it

in their own environment. i feel that when we come back from a home visit, which is usually done in the beginning of the year for the first time, i'm able to understand the parent and the child better. hendrick: many of us, especially those who work with infants, are the child's and the parents' first real contact with the outside world. this presents us with a unique opportunity for becoming closely involved and attached to our infants and family members. hi. hi. but how do we form a bond with our children without becoming overly attached? where do we begin? we can start by making sure the lines of communication between ourselves and the family members are wide open. he has not eaten this morning. he was a good little boy, even though his sister woke him up. sissy wake you up? yes, she did. did sissy wake you up this morning? he's probably hungry. are you hungry? hendrick: one way is by looking for opportunities to find out what's happening at home. families are under a great deal of stress these days for any number of reasons. they might regret having to leave their child with
